1. Products that have been safety-certified should be selected, and the quality of the products of the big manufacturers can be guaranteed.
2. From the perspective of the outer packaging, it should be exquisite in appearance and exquisite in printing. The name of the factory, the address of the factory, the telephone and the manual are complete. Check the appearance of the lamp. The plastic part of the lamp should be clearly marked with the source mark (which can be the name of the trademark or manufacturer), the rated voltage and voltage range, the rated power, and the rated frequency. The bulb of the lamp should be clean. No bubble; the phosphor coating in the tube should be fine, no particles, and even white; the lamp and the tube should be vertical, there should be no inclination; the tube should be firmly connected with the plastic, should not be loose ; shaking the whole lamp by hand should not be loud.
3. The plastic casing of the electronic energy-saving bulb must be made of flame-retardant engineering plastic, and ordinary plastic is forbidden for the production of energy-saving lamps. In addition, as a whole, a plurality of lamps can be put together for comparison, and the shape and size consistency of the lamps are mostly mass-produced products, and the quality is guaranteed. At the same time, the casing should not be cracked or loose, and there should be no damage at the seal.
4. From the perspective of startup performance. If you have a regulator at the time of purchase, first adjust the regulator to 150V (or the minimum starting voltage indicated on the instruction manual) in the power-off state, install an energy-saving lamp, keep your hands and body away from the lamp, and switch on. It should be able to ignite once after the power supply. Because the energy-saving lamp starts to have two characteristics: First, the higher the temperature, the easier it is to start; the second is that it is easy to start under the effect of human body induction. It is worth mentioning that many energy-saving lamps are on and off, which is also unfavorable for the life of the lamp. The energy-saving lamps should have a filament preheating circuit inside, which should have a startup delay time of about 0.4 seconds.
5. Look at the anti-jamming situation. Electromagnetic compatibility is a must-have for home appliances. When the user purchases, it should be checked whether there is a mark on the package that has passed the national electromagnetic compatibility test.
6. Under normal working conditions, the temperature rise of the electronic energy-saving bulb should be low. Otherwise, the life of the energy-saving lamp will be short. At the same time, when the energy-saving lamp is lit, the two ends of the lamp are black, the filament is red or flashing, which indicates that the energy-saving lamp has quality problems.
7. The electronic energy-saving light bulb should first be used before use. At present, most energy-saving lamps in China cannot be used for dimming circuits. Therefore, the warning should be indicated in the instructions for use. In addition, since the energy-saving lamp contains a ballast circuit, it is best not to use it where it is necessary to switch the light source frequently.
8. When purchasing energy-saving lamps, you should not only consider the price, regardless of quality. Some companies are based on the customer's psychology, producing a variety of grades of products, how much money you want to give you what grade of light, if you simply pursue low prices, it is likely to buy unqualified products into the home.
